Use "butt" linecap to workaround split lines in printout (bug #53229). * gl-render.cc (opengl_renderer::draw_axes_grids): Set linecap "butt" to avoid split line intersections where transparency may occur. (opengl_renderer::draw_axes_boxes): Set linecap "square" here to fake polyline intersections at the corners.
